texas
are
still searching
anxiously for suspects of the unsolved killings of two prosecutors. the latest, a

d.a. and his wife, gunned down one week ago today.
charles
hadlock joins us now from kaufman,
texas
, with the latest.
charles
, good morning.

>> reporter: good morning, lester. as a possible sign of how desperate authorities have become for information in this case, the reward has been raised to $200,000. and for investigators looking for facts, the case looks like a broken puzzle. a
texas
-style farewell in mike mclelland's hometown, 70 miles from where the prosecutor and his wife, sintda, were gunned down a week ago. cynthia was cremated and her ashes placed inside her husband's coffin.

>>these were two tremendously good and moral people who served the community so well.

>> reporter: one week after the killings, authorities appear no closer to solving the murders than they were to solving the shooting death of his top assistant, mark hasse, two months ago. no raefs have been made and authorities say they have no suspects. investigators have said little about the murders as they search for a definitive link between the two cases.

>>at this time, we're looking at everything available, every single avenue and not leaving any stone unturned.

>> reporter: the killings tear at the fabric of small-town life and at the system of
law and order
.
texas governorrick perry
had a promise for the person or group responsible.

>>we're going to hunt you down. we're going to punish you and do our best to remove that type of threat.

>> reporter: as the mclellands were laid to rest, the sheriff in charge of the investigation was still trying to make sense of it all.

>>i think we would understand if it was an accident and everything, but deliberate carnage -- that's the only way to put this kind of thing, i think. it's unimaginable.

>> reporter: and information about that $200,000 reward in this case goes up on digital billboards across the country this week. lester?
